guys recently i spoke to an airtel cc executive reg. Double speed upg. during june. I was told dat dis is only for 256kb/s customers who get 512kb/s upto 5gB , after which the speed reverts back to 256kb/s. For other customers there is no speed upgrade. Is this true ? I had to believe in this cuz unlike the BS bsnl cc they dont give wrong info. what do you guys think about this ?
